Referring to fig. 1 to 6, an embedded emergency canister lamp according to a preferred embodiment of the present invention will be described in detail below, wherein the embedded emergency canister lamp includes a lamp body 10, a lens 20, and a lens pressing member 30, wherein the lamp body 10 includes a lamp socket 11, a first circuit board 12, and a light emitting member 13. The lamp holder 11 is provided with a light outlet 111. The first circuit board 12 is preferably implemented as a PCB board and is fixedly disposed on the lamp socket 11, and the light emitting member 13 is preferably implemented as an LED lamp mounted on the first circuit board 12, and the light emitting member 13 faces the light emitting hole 111, so that light can be emitted to the outside through the light emitting hole 111 after power is applied to emit light.
The lens 20 is attached to the surface of the first circuit board 12 and covers the light emitting element 13, so that a predetermined light spot can be provided through the lens 20 after the light emitting element 13 emits light, and a certain lighting atmosphere can be provided. Meanwhile, the outer diameter of the lens 20 is smaller than the aperture of the light outlet 111, so that the lens 20 can be taken out from the light outlet 111, and other lenses can be replaced conveniently, so that the whole emergency down lamp is prevented from being detached, the emergency down lamp can be kept in a first-time installation state, and when the lenses are replaced frequently in the later stage to provide different light spots to obtain different illumination atmospheres, the inherent structural stability of the installation point of the emergency down lamp is effectively protected, the inherent fireproof capacity, waterproof capacity, structural stability and other good performances of the emergency down lamp are maintained, time and labor are saved, and the use cost is greatly reduced. In addition, on an uninstalled emergency down lamp, the lens 20 can be quickly replaced to enable the emergency down lamp to be installed in different application environments, so that the application range is wide.
The lens compressing member 30 is rotatably and detachably arranged on the lamp holder 11, and the lens compressing member 30 is matched with the light emitting hole 111 and the lens 20, so that the lens compressing member 30 can seal the light emitting hole 111 after being mounted on the lamp holder 11 and compress the lens 20 on the surface of the first circuit board 12, and after the lens compressing member 30 is detached from the lamp holder 11, the lens 20 can be taken out through the light emitting hole 111, thereby effectively improving the fastening capability and safety performance of the lens 20 in a rotary compressing manner, and not directly performing overturn type compression (the overturn type compression is easier to be detached to reduce the protection safety standard), and the operation is more convenient, and dismounting marks are not easy to form on the surface of the lamp holder 11.
In addition, in one embodiment, the lens 20 and the lens pressing member 30 are both located in the light emitting hole 111, so that the emergency down lamp has a more compact structure, reduces the occupied space, and has a more ornamental effect when in use. Meanwhile, considering that the lens 20 used in the lamp is mostly of a structure with a middle protruding outwards, in order to effectively fasten the lens 20, the lens pressing member 30 is implemented as a pressing ring, so that the lens 20 is pressed on the outer circumference of the lens 20 by the lens pressing member 30, and the lens 20 can be uniformly and compactly attached to the surface of the first circuit board 12, so that the lens 20 is effectively fastened, dislocation or shaking is not easy to occur, and a high-quality and stable illumination atmosphere can be provided.
In a preferred embodiment, the lens pressing member 30 is provided with at least two clips 31 at intervals along the circumferential direction. Such as two snaps 31 or three snaps 31, wherein a plurality of the snaps 31 are preferably evenly distributed circumferentially to provide a uniform restraining force. The lamp holder 11 is formed with a limit structure 112 in the light outlet 111, which is matched with the buckle 31. The limiting structure 112 includes a rotation notch 1121, a limiting plane 1123, and a rotation gradient 1122 extending from the rotation notch 1121 to the limiting plane 1123 gradually and obliquely, wherein the limiting plane 1123 is close to the first circuit board 12. When the lens pressing member 30 is rotatably mounted, the buckle 31 on the lens pressing member 30 is first screwed in by the rotation notch 1121, and then gradually rotates to the position of the limit plane 1123 by the rotation gradient 1122, so that the gradual pressing of the lens 20 is realized by the rotation gradient 1122, and the impact on the lens 20 when pressing the lens 20 is reduced.
It should be noted that the limit plane 1123 is preferably implemented parallel to the surface of the lamp socket 11, i.e., the limit plane 1123 is preferably implemented to extend in a horizontal direction, so as to provide a continuous stable pressing force to the lens 20 when the catch 31 on the lens pressing member 30 is rotated to the limit plane 1123. On the other hand, the limiting plane 1123 is preferably implemented as a plane having an included angle with respect to the horizontal direction, for example, an included angle of 3 ° -10 °, and the limiting plane 1123 is gradually inclined from the rotational slope 1122 toward the other side away from the rotational notch 1121 toward the direction approaching the first circuit board 12, so that the pressing force on the lens 20 can be gradually increased as the clip 31 moves on the limiting plane 1123 when the lens pressing member 30 is rotated.
Further preferably, the limiting plane 1123 is provided with at least one self-locking groove 1124 along the circumferential direction of the limiting structure 112, and an arc curved surface transition is formed between the notch of the self-locking groove 1124 and the limiting plane 1123;
The side of the buckle 31 near the limiting plane 1123 is provided with a soft convex hull 311, wherein the soft convex hull 311 is preferably made of PC material, so as to provide good mechanical properties, such as high strength and elastic coefficient, high impact strength, good fatigue resistance, good dimensional stability and small creep (little variation under high temperature conditions). The soft convex hull 311 is matched with the self-locking groove 1124. When the lens pressing member 30 is rotated, the buckle 31 moves on the limiting plane 1123, the soft convex hull 311 is compressed, and when the buckle 31 moves to the self-locking groove 1124, the soft convex hull 311 bounces back into the self-locking groove 1124, so that self-locking of the buckle 31 and the limiting structure 112 is realized. Only when the external force overcomes the force of the soft convex hull 311 separating from the self-locking groove 1124, the soft convex hull 311 on the lens pressing member 30 can be screwed out from the self-locking groove 1124, and the buckle 31 must be moved through the limiting plane 1123, the rotating gradient 1122 and the rotating notch 1121 in sequence, so that the lens pressing member 30 can be rotationally detached from the lamp holder 11. Therefore, by the cooperation of the soft convex hull 311 and the self-locking groove 1124, the lens pressing piece 30 performs pressing and self-locking on the lens 20, so that the emergency tube lamp has a higher safety protection level and is not easy to be disassembled easily.
Further preferably, the limiting plane 1123 is provided with at least two self-locking grooves 1124 at predetermined intervals along the circumferential direction of the limiting structure 112 from the rotation notch 1121, and the surface of the lamp holder 11 away from the first circuit board 12 is provided with a mark 14 corresponding to each self-locking groove 1124, that is, with the center of the lens 20 as the center, and a plurality of marks 14 corresponding to a plurality of self-locking grooves 1124 are disposed at predetermined rotation angles, for example, 0 °, 20 ° 45 °, that is, with the rotation notch 1121 as the origin, and each of the self-locking grooves 1124 is disposed at intervals of 20 ° and 45 °.
When the limiting plane 1123 extends in the horizontal direction, the self-locking forces of the self-locking grooves 1124 at 20 ° and 45 ° on the lens pressing member 30 are uniform. However, if the catch 31 is rotated to the 45 ° self-locking groove 1124, it is necessary to pass through the 20 ° self-locking groove 1124 during the disassembly process, and then move along the limit plane 1123 and the rotation slope 1122, and then the catch is removed from the rotation notch 1121, that is, it is necessary to apply two forces to overcome the self-locking forces of the 45 ° self-locking groove 1124 and the 20 ° self-locking groove 1124, respectively, which means that the two self-locking grooves 1124 have a higher protection level with respect to one self-locking groove 1124. Furthermore, as mentioned above, when the limiting plane 1123 forms a certain angle with the horizontal direction, the self-locking groove 1124 located at 45 ° and the limiting plane 1123 near the self-locking groove 1124 have a larger limiting force, i.e. can provide a larger pressing force to the lens 20, which means that the lens pressing member 30 can form self-locking at the self-locking groove 1124 at 45 ° and further can provide a stable and larger pressing force to the lens 20. Therefore, the 45 ° self-locking groove 1124 on the inclined extending limiting plane 1123 can provide substantially the same self-locking stability compared with the 45 ° self-locking groove 1124 on the horizontal extending limiting plane 1123, but the pressing force of the 45 ° self-locking groove 1124 on the inclined extending limiting plane 1123 on the lens 20 is stronger, that is, the stability of the lens 20 is higher, and the overall structure of the emergency down lamp is more stable.
In addition, as described above, when the limiting plane 1123 has a certain inclination angle, a plurality of self-locking grooves 1124 may be uniformly disposed along the extending direction of the limiting plane 1123, so that different pressing forces for the lens 20 may be performed at each self-locking groove 1124, so that the pressing force for the lens 20 may be flexibly adjusted by the lens pressing member 30, and after the adjustment is in place, the provided pressing force is a continuous and stable pressing force, so as to ensure the illumination stability of the emergency down lamp, so that the emergency down lamp is suitable for installing lenses with different specifications or different installation requirements, and has a wider application range.
Further preferably, a side of the limit structure 112 away from the first circuit board 12 is kept at a predetermined distance from the surface of the lamp socket 11, forming a stepped structure 1125;
The periphery of the lens compressing member 30 is provided with a reinforcing rib plate 32 having the same thickness as the predetermined distance, and the distance between the reinforcing rib plate 32 and the buckle 31 is equal to the thickness of the limiting structure 112, so that the limiting structure 112 is clamped by the cooperation of the reinforcing rib plate 32 and the buckle 31, and the compression stability of the lens compressing member 30 to the lens 20 is further improved. In addition, when the lens 20 is impacted by external force, the limiting structure 112 can also provide a certain supporting effect for the reinforcing rib plate 32, so that the impact force of the lens pressing member 30 on the lens 20 is effectively reduced, and even the impact of the lens pressing member 30 on the lens 20 is avoided, and the lens 20 is protected.
Further preferably, the reinforcing rib plate 32 is matched with the wall of the light emitting hole 111 in the circumferential direction, so as to further improve the tightness of the lens pressing member 30 to the light emitting hole 111, and make the connection relationship between the lens pressing member 30 and the lamp holder 11 more stable. In addition, the reinforcing rib plate 32 is provided with a rotation groove 321 facing the buckle 31 so as to rotate the lens compressing member 30. The reinforcing rib plate 32 is symmetrically provided with clearance notches 322 on the side surface of the rotating groove 321, which is close to the buckle 31, so that the space distance between the reinforcing rib plate 32 and the buckle 31 is enlarged. Meanwhile, the opening size of the clearance gap 322 is larger than the length size of the buckle 31, so that the buckle 31 is easier to be processed and formed through the forming die when the emergency down lamp is processed, the forming quality of the buckle 31 is easier to be ensured, the reject ratio is reduced, and the waste of resources and the processing cost are reduced. When the lens pressing member 30 is rotated by the rotating groove 321, a rotating tool or a finger of a person can also extend into the gap 322 to increase the supporting area for rotation, thereby facilitating rotation.
In another preferred embodiment, the lamp body 10 further includes a heat dissipation member 15 and a plastic rear housing 16, wherein the heat dissipation member 15 is disposed on a side of the first circuit board 12 away from the lamp base 11, so as to enhance the heat dissipation effect on the first circuit board 12. The lamp holder 11 is integrally extended with a clamping groove 113 adapted to clamp the heat dissipation member 15, so as to facilitate the disassembly of the heat dissipation member 15 and improve the working efficiency. The plastic rear shell 16 is coated on the surface of the heat dissipation element 15 and detachably connected with the lamp holder 11, so as to protect the heat dissipation element 15 and improve the fireproof and waterproof performances of the emergency down lamp.
In addition, at least two snap springs 161 are symmetrically arranged on the outer surface of the plastic rear shell 16 along the circumferential direction, so that after the emergency down lamp is installed in place, the emergency down lamp is directly clamped on a ceiling or other installation targets through the snap springs 161, and the emergency down lamp is effectively fixed.
In addition, at least two buckles, such as two or three buckles symmetrically arranged, are further arranged at intervals on the periphery of the lamp holder 11 along the circumferential direction, and meanwhile, the plastic rear shell 16 is provided with buckle grooves or buckle holes matched with the buckles, so that the plastic rear shell 16 is rapidly detached or installed on the lamp holder 11 through the cooperation of the buckles and the buckle grooves or the buckle holes.
Preferably, the lamp body 10 further includes an external connection wire 17, an external power supply 18, and a metal power supply box 19 covering the external power supply 18, wherein the first circuit board 12 is electrically connected to the external power supply 18 through the external connection wire 17, and two ends of the external connection wire 17 are respectively provided with a hose connector 171, so as to facilitate quick connection, and the external connection wire 17 and the hose connector 171 are metal pieces, so as to provide high fireproof performance, conform to safety regulations, and provide a large application range.
